Without an open book system, school becomes midless memorization

In the real world books are always available to be used for research and study. There is a difference between the ability to memorize information temporarily, and it is another to learn how to use a book as a reference. There is no need for mindless memorization. Children should be taught with an open book system.

Open book works well if done properly.

A well constructed open book test can be much more challenging and teach a child more than simply forcing them to memorize sections. Knowing how to find and interpret information is a much needed skill that will serve them well. Asking them to memorize a chapter then ask specific questions might only teach them to memorize that chapter, but asking a challenging question that they have to really dig into the book and draw conclusions can implant concepts that last a lifetime.
